Check the belt for wear, cracks or other signs of damage.
If any of the following defects is found, replace the V-ribbed belt.

1. The belt is cracked.
   
2. The belt is worn out to the extent that the cords are exposed.
   
3. The belt has chunks missing from the ribs.
   

Check that the belt fits properly in the ribbed grooves.

HINT:

Check with your hand to confirm that the belt has not slipped out of the grooves on the bottom to the pulley. If it has slipped out, replace the V-ribbed belt. Install a new V-ribbed belt correctly.

Check the V-ribbed belt deflection and tension.

Standard Deflection:

Item	Specified Condition

Used belt	7.6 to 10.0 mm (0.299 to 0.394 in.)

Standard Tension:

Item	Specified Condition
New belt	700 to 800 N (70 to 80 kgf, 157.4 to 179.8 lbf)
Used belt	550 to 750 N (55 to 75 kgf, 123.6 to 168.6 lbf)

HINT:

1. When inspecting the V-ribbed belt deflection, apply 98 N (10 kgf, 22.0 lbf) of tensile force to it.
   
2. Check the V-ribbed belt deflection at the specified point.
   
3. V-ribbed belt tension and deflection should be checked after 2 revolutions of engine cranking.
   
4. Measure the belt tension when the engine is cold.
   
5. When adjusting the belt, be sure to adjust it so that the tension is as close as possible to the median of the specified range.
   
6. When replacing the belt with a new one, be sure to perform the following after adjusting the belt: idle the engine for 5 minutes, and then adjust the belt to the specified value for a new belt after the engine has cooled.
   
7. When inspecting a belt which has been used for over 5 minutes, apply the used belt specifications.
   
8. When using a belt tension gauge, confirm its accuracy by using a master gauge first.
   

Tighten the radiator drain cock plug by hand.

Tighten the water drain cock plug.

Torque:

Add TOYOTA Super Long Life Coolant (SLLC) to the radiator reservoir filler opening until it is filled to the B line at the base of the reservoir filler neck.

HINT:

The B line is the lower edge of the inner wall of the filler neck.

Standard capacity:

Item	Specified Condition
for Manual Transaxle	5.8 liters (6.1 US qts, 5.1 Imp. qts)
for CVT	6.0 liters (6.3 US qts, 5.3 Imp. qts)

HINT:

TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology is a combination of low phosphates and organic acids).

NOTICE:

Never use water as a substitute for engine coolant.

Press the No. 1 and No. 2 radiator hoses several times by hand, and then check the level of the coolant. If the coolant level drops below the B line, add TOYOTA SLLC to the B line.

Install the radiator reservoir cap.

Start the engine and warm it up until the cooling fan operates.

1. Set the air conditioning as follows while warming up the engine.
   
   

   Measurement condition

   Item	Condition
   Manual Air Conditioning System	Fan speed: Any setting except off Temperature: Toward WARM Air conditioning switch: Off
   Automatic Air Conditioning System	Temperature: Toward MAX (HOT) Air conditioning switch: Off

2. Maintain the engine speed at 2000 to 2500 rpm and warm up the engine until the cooling fan operates.
   

   NOTICE:

   1. Make sure that the radiator reservoir still has some coolant in it.
      
   2. Pay attention to the needle of the coolant temperature meter. Make sure that the needle does not show an abnormally high temperature.
      
   3. If there is not enough coolant, the engine may burn out or overheat.
      
   4. After starting the engine, if the radiator reservoir does not have any coolant, perform the following: 1) stop the engine, 2) wait until the coolant has cooled down, and 3) add coolant until the coolant is filled to the B line.
      
   5. Run the engine at 2000 rpm until the coolant level has stabilized.
      

Press the No. 1 and No. 2 radiator hoses several times by hand to bleed air.

CAUTION:

When pressing the radiator hoses:

1. Wear protective gloves.
   
2. Be careful as the radiator hoses are hot.
   
3. Keep your hands away from the radiator fan.
   

Stop the engine and wait until the coolant cools down to ambient temperature.

Check that the coolant level is between the FULL and LOW lines. If the coolant level is below the LOW line, repeat all of the procedures above.
If the coolant level is above the FULL line, drain coolant so that the coolant level is between the FULL and LOW lines.

Remove the radiator reservoir cap.

CAUTION:

To avoid the danger of being burned, do not remove the radiator reservoir cap while the engine and radiator are still hot. Thermal expansion will cause hot engine coolant and steam to blow out from the radiator reservoir.

Fill the radiator and reservoir with coolant, and then attach a radiator cap tester.

Warm up the engine.

Pump the radiator cap tester to 118 kPa (1.2 kgf/cm², 17.1 psi), and then check that the pressure does not drop.
If the pressure drops, check the hoses, radiator and water pump for leakage.
If there are no signs of external coolant leaks, check the heater core, cylinder block and head.

Reinstall the radiator reservoir cap.

Attach the 4 clips to install the cover.

NOTICE:

1. Be sure to attach the clips securely.
   
2. Do not apply excessive force or do not hit the cover to attach the clips. This may cause the cover to break.
   

Install the radiator support opening cover with the 9 clips.

Install the under cover with the 3 clips.

Install the under cover with the 6 screws and 10 clips.
